The production, which explores domestic violence, also won Best Actor and Best Actress for Tomasz Schuchardt and Agata Turkot.
The highlight of the evening came when Krystyna Janda, one of Poland's best-loved actresses, received a lifetime achievement award.
Janda, who has appeared in more than 60 films and runs two Warsaw theatres, first found fame in Andrzej Wajda's classic Man of Marble back in 1976.
The ceremony – the 28th of its kind – took place at the Arnold Szyfman Polish Theatre in the capital.
Among the other winners, Piotr Domalewski picked up both best screenplay and the audience award for Ministranci (Altar Boys), while Maciej Drygas won best documentary for Pociągi (Trains).
The best drama series prize went to Jan Holoubek's Heweliusz, and Spanish film Sirat by Oliver Laxe took the best European film award.
First-time director Emi Buchwald was named discovery of the year, and Mikołaj Trzaska won best score for Dom dobry.
The Polish Film Awards, known as the Eagles (Orły), were established in 1999 to celebrate the best of domestic cinema.
